Abstract
Embodiments of the invention provide a dermatological cosmetic treatment and imaging system and method. In some embodiments, the system (20) includes a hand wand (100) with at least one finger activated controller (150, 160), and a removable transducer module (200) having an ultrasound transducer (280). In some embodiments, the system (20) can include a control module (300) that is coupled to the hand wand (100) and has a graphical user interface (310) for controlling the removable transducer module (200), and an interface (130) coupling the hand wand (100) to the control module (300). The interface (130) may provide power to the hand wand or may transfer a signal from the hand wand to the control module. In some embodiments, the cosmetic treatment system (20) may be used in cosmetic procedures on at least a portion of a face, head, neck, and/or other part of a patient.
